How the Furuno SCX20 Works
The SCX20 utilizes dual-antenna GNSS technology to determine the vessel’s heading with extreme precision. By comparing the relative position of the two antennas via satellite signals, it calculates true heading and attitude data unaffected by the Earth’s magnetic field anomalies or vessel magnetic interference.
This information is then transmitted through the NMEA2000 network, enabling real-time sharing with other onboard electronics, enhancing situational awareness and navigation safety.

Detailed FAQ Section
What is the main difference between the Furuno SCX20 Satellite Compass and a traditional magnetic compass?
The primary difference lies in the technology used to determine heading. The Furuno SCX20 Satellite Compass uses dual-antenna GNSS technology to calculate true heading by referencing satellite signals, which is unaffected by magnetic interference common in steel hulls or electronic equipment. Traditional magnetic compasses rely on the Earth’s magnetic field and can be distorted by nearby magnetic objects or vessel structures, leading to inaccurate readings. The SCX20 delivers more reliable and precise heading data, essential for modern marine navigation systems integrated with autopilots and chartplotters.
How do I install the Furuno SCX20 Satellite Compass on my boat?
Installing the Furuno SCX20 requires careful selection of a mounting location with a clear, unobstructed sky view to ensure optimal satellite reception. The device should be securely attached to a stable, vibration-free surface. Connect the unit to your vessel’s NMEA2000 network using the proper connectors and cables. After powering on, the device will automatically calibrate and start transmitting heading and attitude data. It is recommended to follow the official Furuno installation guide for detailed steps and safety precautions. Proper installation is key to achieving accurate and reliable compass performance.
What maintenance is required for the Furuno SCX20 Satellite Compass?
Regular maintenance includes cleaning the unit’s exterior to remove salt, dirt, and other residues that accumulate in a marine environment. Periodically inspect the NMEA2000 connectors and cables for corrosion or damage. Firmware updates released by Furuno should be applied promptly to maintain functionality and address any bugs. Additionally, it is good practice to verify compass calibration and heading accuracy during routine vessel maintenance checks, especially after heavy weather or modifications to the vessel’s structure that could affect sensor performance.
Can the Furuno SCX20 Satellite Compass be used with autopilots?
Yes, the Furuno SCX20 is designed for seamless integration with autopilot systems through its NMEA2000 output.
